I have added my time machine volume on my external drive to the "do not scan" part of the auto protect, but it does absolutely no good and will start scanning every time the drive is plugged in. I tried adding the backup file on the drive as well to no avail. Any suggestions?
Plugging in the Time Machine drive is triggering an Auto Disc Scan on mount event.
Given the current design of the product your only recourses are:
1) Leave your locally connected Time Machine drive permanently attached, so that there are no mount events happening while your computer is booted.
2) Use a networked Time Machine drive. The Norton product apparently DOES ignore attaching to a networked Time Machine drive each time a networked Time Machine backup starts.
3) Turn off the Auto Disc Scan on mount feature in the Auto Protect portion of Norton Anti-virus. Note that this will disable scan on insertion for ALL discs.
4) Manually cancel out of the disc scan each time you plug in the Time Machine drive.
A better way of handling local Time Machine drives has been requested.

A fifth option is to uncheck the "Show Progress During Scans" option under the Auto Disk Scan settings. The scan will still occur, but silently (unless an infected file is found). The scan should be terminated automatically when the backup completes and the drive is unmounted.
As Bob stated, we are looking at ways to improve this behavior.
